Front Forks Setup

Adjustment Locations on Forks

Rebound adjustment (if applicable) is located near the top of the fork. Compression adjustment (if applicable) is located near the bottom of the fork. Spring preload adjustment (if applicable) is generally hex style and located at the top of the fork.

TroubleShooting

Lack of Rebound

Symptoms:

* Forks are plush, but increasing speed causes loss of control and traction
*

The motorcycle wallows and tends to run wide exiting the turn causing fading traction and loss of control.
*

When taking a corner a speed, you experience front-end chatter, loss of traction and control.
*

Aggressive input at speed lessons control and chassis attitude suffers.
*

Front end fails to recover after aggressive input over bumpy surfaces.

Solution: Insufficient rebound. Increase rebound “gradually” until control and traction are optimized and chatter is gone.

Too Much Rebound

Symptoms:

*

Front end feels locked up resulting in harsh ride.
*

Suspension packs in and fails to return, giving a harsh ride. Typically after the first bump, the bike will skip over subsequent bumps and want to tuck the front.
*

With acceleration, the front end will tank slap or shake violently due to lack of front wheel tire contact.

Solution: Too much rebound. Decrease rebound “gradually” until control and traction are optimized.

Lack of Compression

Symptoms:

*

Front-end dives severely, sometimes bottoming out over heavy bumps or during aggressive breaking.
*

Front feels soft or vague similar to lack of rebound.
*

When bottoming, a clunk is heard. This is due to reaching the bottom of fork travel.

Solution: Insufficient compression. Increase “gradually” until control and traction are optimized.

Too Much Compression

Symptom:

*

Front end rides high through the corners, causing the bike to steer wide. It should maintain the pre-determined sag, which will allow the steering geometry to remain constant.

Solution: Decrease compression “gradually” until bike neither bottoms or rides high.

Symptom:

*

Front end chatters or shakes entering turns. This is due to incorrect oil height and/or too much low speed compression damping.

Solution: First, verify that oil height is correct. If correct, then decrease compression “gradually” until chattering and shaking ceases.

Symptom:

*

Bumps and ripples are felt directly in the triple clamps and through the chassis. This causes the front wheel to bounce over bumps.

Solution: Decrease compression “gradually” until control is regained.

Symptom:

*

Ride is generally hard, and gets even harder when braking or entering turns.

Solution: Decrease compression “gradually” until control is regained.
